Yes, the term BIM is most of the time used incorrectly. What people are missing is in that second let "I", information.
Clash detection is not BIM. What's funny is that most designers think this 3D thing is a new discovery when in fact we've been doing 3D modeling since the early to mid 90's when the big graphic computing power was driven by UNIX based machines with monochrome monitors running Microstation based PDS 3D. But still not a true BIM. Just 3D cad. Clash detection is not BIM. It's just coordination. And Steve, I've taped plenty of drawings to an office window and light table to do coordination. Yup weren't those the days. lol Craig L.

Building Information Modeling, in full working theory, requires that there be engineering attributes to the objects shown. BIM is not NavisWorks - Navis is a 3D emulation viewer that projects 2D AutoCad and other drawing files as 3D to allow clash detection and a rotatable image of the input files. My experience with it has been mixed; we often find that Navis-detected clashes don't exist, but that Navis misses clashes that are found the hard way in the field. Revit offers a full parametric 3D environment, but there's no content out there except for empty skins, that show images of objects such as valves and fittings, but which still don't contain true BIM content. In theory, BIM software such as Revit should give us a platform in which we can calc' the system, list the materials, coordinate our piping with work of all other trades, maintain an archive of part numbers for service and repair, etc., etc. But that depth of content is likely years away so for now, BIM is just a short-hand way of saying "Clash detection effected by 3D software that may or may not result in accurate coordination by trades since it's the epitome of the GIGO model." As for what value that may or may not add to the designer's job description I don't know, but to the designer who says that they don't field survey to check their work I say that we used to overlay our vellums with the sheet metal drawings on a light table or against a large sunny window. We'd mark everything up in pencil as required and then go back to the office and revise appropriately. It took less time, involved direct communication between stakeholders, didn't require a $9,000 software package that runs on a $4,000 computer, nor the involvement of a $175 per hour "consultant" to misread the results of the computer model. Unfortunately for my firm, 90% of our work is for architectural clients who are romanced by BIM, so we're stuck in the vortex.
